Diamond Shapes: Pear Cut Diamond

The technical name of the pear is "pear-shaped modified brilliant," based on its shape and modifications of the traditional round brilliant configuration. A hybrid cut, combining the best of the Round Brilliant and the Marquise, it is shaped like a sparkling teardrop.

The pear shape usually has the 58 facet brilliant pattern, but can be cut with different numbers of pavilion mains of 8, 7, 6, or 4 facets. The teardrop shape has a round or oval shape on half the facet pattern while the other half resembles a marquise with the sides tapering to a point.
The first pear-shaped diamond was created in the 1400s by Flemish cutter Lodewyk van Berquem of Bruges, inventor of the diamond-polishing wheel, or scaif.

This invention enabled him to polish all the facets of the diamond to optimize light reflection within it. It was from this watershed moment onwards that diamonds began to be used in jewellery.

Van Berquem also pioneered the now common place symmetrical arrangement of facets on a stone, this in turn led him to fashion the pear-shaped "Pendeloque" or "Briolette" cut.

When purchasing a Pear Shaped Diamond, it's extremely important to pay attention to quality and to select the highest grade cut you can afford.

In a pear, look for a well-shaped head and even shoulders with a length-to-width ratio of 1.45-1.70. Pear-shaped diamonds work great for pendants and drop earrings.

The optimal pear shape is one with a polished girdle and a rounded base, or “even shoulders”. However, much like the oval cut, a more attenuated pear shape may elongate the fingers, so it is important to reconcile these two qualities. Additionally, colour is often more visible towards the tip of the pear shape, so to ensure an even tone throughout the stone it is advisable to opt for colours H and above.

Diamond Shapes: Emerald Cut Diamond

The "emerald" cut of diamond is another square or rectangular shaped diamond. As opposed to the brilliant cut, however, with its triangular or four sided diamond cut facets, the "emerald" cut of diamond has step cut facets. The term "step cut" refers to the step-like look of the facet cuts.

The emerald cut has 58 facets (25 crown, 8 girdle and 25 pavilion). Because of the angle, size and shape of the facets, the emerald cut shows less brilliance and fire (dispersion) than the other brilliant cut diamonds. However, the emerald cut stone reveals a classic beauty and elegance not seen in other cuts. The look of an emerald cut diamond is subtle and understated with less "flash," or reflection and refraction than brilliant cuts.
 
Aspect ratio of an Emerald Cut: The ratio of the length to the width should be about 1.5:1 and the VS1-2 range is recommended as a minimum Emerald cut diamonds are often 'paired' with other side stones.

The emerald cut diamond can be absolutely stunning. Because of it's long lines, it tends to be less fiery than a "round brilliant" cut, but it also tends to have broader, more dramatic flashes of light. The trim lines of emerald cut diamonds lend an elegant, sophisticated air to both the simplest and most elaborate ring settings.

Because of its large open facets, higher clarity grades (VS2 and above for GIA and VS1 and above for EGL, to ensure it is completely eye clean) are usually recommended for emerald cut diamonds.

As with the Asscher and Cushion cuts, more rectangular shapes (larger ratios) help to elongate shorter fingers.

The emerald cut is also one of the most popular and widely available non-round cuts, so you shouldn’t have too much trouble finding a decent variety of emerald cut diamonds from which to choose. Furthermore, in part because the emerald cut generally isn’t considered an “ideal” cut in the same way that the round brilliant is, emerald cut diamonds can be markedly more affordable than otherwise comparable round diamonds.

Diamond Shapes: Princess Cut Diamond

The Princess Cut, technically known as "Square Modified Brilliant Cut", is a square version of the Round Brilliant Cut. It may have either 50 facets (21 crown, 4 girdle, 25 pavilion) or 58 facets (21 crown, 4 girdle, 33 pavilion), depending on how the pavilion is cut. This cut is most frequently a square shape where the length to width ratio is 1.05 or less.

According to Harold Newman's "Illustrated Dictionary of Jewellery", the term Princess Cut was previously applied to what is now known as the "Profile Cut" developed by Arpad Nagy of London in 1961. The same name was later used and made popular by Ygal Perlman, Betzalel Ambar, and Israel Itzkowitz in Israel, who in 1979 created the Princess cut (or Square Modified Brilliant) as it is known today.

The Princess Cut was designed for weight retention of octahedral Diamond crystals, helping to create more attractive Diamonds at more reasonable prices.

The princess cut tends to be one of the smallest of the shapes for the same carat weight since the cut is basically an upside-down pyramid with most of the carat weight in the pavilion. Princess cut diamonds with larger total depth percentages are much smaller in length and width than lower depth stones.

Always ensure that the setting for your princess cut diamond protects the four pointed corners -- these are the points most likely to chip (and why most rectangular or square diamond cuts have cropped corners).

Because of its extra facets, the Princess cut can disperse more light through the stone, this serves to hide inclusions more efficiently, making it the most brilliant of all square- and rectangular-shaped stones. It is also a popular cut for wedding bands because the stones can be arranged side by side without any gaps, making it ideal for an eternity band too. Furthermore, due to its sharply squared corners, the Princess is an ideal cut for long fingers.

Diamond Shapes: Round Brilliant Cut Diamond

The rounds brilliant is the most popular of the diamond shapes. It is also the most brilliant of all the cuts. You may have heard of a term called “Ideal Cut“. This term refers to the attempt to cut a round diamond into the best proportions to achieve maximum brilliance. Today’s modern round brilliant diamond is precisely cut to maximize the diamond’s brilliance, fire and size.




The modern round brilliant diamond consists of 56-58 facets including the culet. Between the table and the girdle are generally thirty-two facets, and below the girdle twenty-four. The facets maximize the volume of light that is reflected from the inside and produce the greatest brilliance.

The round diamond began to rise in popularity in 1919 with the publication of Marcel Tolkowsky’s thesis “Diamond Design: A Study of the Reflection and Refraction of Light in Diamond”. Tolkowsky’s work described the ideal proportions of a round cut diamond for maximizing light return (or brilliance) and dispersion (or fire). The original Tolkowsky specifications (53% table, 59.3% depth, 34.50 crown angle, visible culet) have since been modified as the cut mechanics for round diamonds have perfected over time. These theoretical advancements, as well as advancements in technology (such as the use of lasers in diamond cutting), have been adopted by diamond manufacturers to produce the incredibly brilliant cuts we see today in well cut round diamonds.

Because of the popularity of round diamonds, all diamond stores are well-stocked with round diamonds, providing customers with the greatest range of flexibility in terms of balancing cost versus quality. In other words, whether you are on a limited budget or the “sky’s the limit”, you will likely be able to find a suitable Round Brilliant Diamond in your price range at most stores.

The round brilliant is the most versatile of all cuts both in terms of style and value. With more fire and brilliance than any other shape, this cut offers the ideal balance between cut, colour and clarity grades and budget.
For a bachelor unsure of what might please his lady, it is hard to go wrong with this classic choice.
